JUDSON T. WEST, OF HOPE, ARKANSAS.

FLOORING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 327,842, dated October 6, 1885.

Application filed July 30, 1885. Serial No. 173,051.

To all whom it may concern.-

Be it known that I, J UDsoN T. WEST, a citizen of the United States of America, residing at Hope, in the county of Hempstead and State of Arkansas, have invented certain new and useful Improvements in Flooring-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has relation to flooring-machines; and it consists of an automatic attachment thereto which edges the lumber to a uniform width, according as set, and which is automatically brought down to its work when there is an edge to be cut off, and then automatically rises out of the way when there is no work to be done.

In the accompanying drawings, Figure 1 is a top plan View of the attachment attached to a flooring-machine. Fig. 2 is a side elevation of the same attached to a flooring-machine, a part of the machine-frame being cut away to show the attachment. Figs. 3, 4, 5, and 6 are detail views, all of which are hereinafter more fully described.

1 and 2 are bars, the rear ends of which are pivoted to the frame 3 of the machine by a bar, 4, the inner end of which is supported by passing through the said frame and the outer end by braces 5. To the front end of these bars 1 and 2 is attached a bar, 6, and to either end of the bar 6 is attached the gudgeon-boxes 7, which bear the shaft 8. This shaft 8 has on its outer end a pulley, 9,which is operated by a band from an extra pulley, 10, on the driving-shaft of the flooring-Inachine. On the other (the inner) end is the circular saw 11, the office of which is to cut off the edges of the lumber as itpasses through the flooring-machine, reducing the width of all planks to a particular gage. On either side of the saw 11 are washers 12, to enable the saw to be set to any gage. On the top of the frame 3 is pivoted, onbraces 13,a balancebeam, 14, having adjustable weights 15, and to the front end of the balance-beam is pivoted a hook, 16, which hooks into the bowed part 17 of the beam 6.

On the inside of the frame3 is bolted to (N0 model.)

the bar 2, at a point between the beam 6 and the rear rollers, 18, a bar, 19, which is curved upward, passing over thebeam 6, and then downward under the shaft 8, and terminating at a point, 20, parallel with the upper end of the bar 2. To the outer end of this bar 19 is pivoted a bar, 21, which extends downward until its lower end is parallel with the shaft of the lower rear roller, 18. To the lower end of this bar 21 is pivoted one end of a bar, 22, the other end of which is pivoted around the shaft of the said lower roller, 18. On the other end of said lower roller, 18, one end of a bar, 23, is pivoted, the other end of which is welded to one end of the transverse bar 24, the other end of which is welded to the bar 22 near its middle. On this transverse bar 24 is secured an arm, 25, in the upper end of which is pivoted a friction-roller, 26. This arm 25 may be set at any point on the said transverse bar 24 by means of the set-screw 27.

Having described my invention, I will now proceed to explain its operation: The saw is first set to the gage desired, and then the friction-roller is set to the proper gage. \Vhen the plank passes between the two front rollers, 28, its front end comes in contact with the friction-roller 26. This bears the whole attachment down, and brings the saw 11 in contact with the plank, which cuts off the edge, and when the plank passes beyond the said friction-roller the attachment is raised again by means of the adjustable weights 15 on the balance'beam 14.

If there is no edge to be cut off the lumber, the plank will not come in contact with the friction-roller, and the saw will not be brought down.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with a flooring-machine, of the edging attachment consisting of the bars 1 and 2, pivoted to the frame 3 of said flooring-machine by the bar 4, and bearing on their front ends beam 6, supporting gudgeon-boxes 7, bearing the shaft 8, circular saw 11, borne on said shaft and gaged by washers 12, bars 22 and 23, to which is welded the transverse bar 24, arm 25, hearing in its up- In testimony whereof I affiX my signature in per end the friction-roller 26, hook 16, its presence of two Witnesses. lower end hooked under the beam 6 and its 2 upper end pivoted to the short end of the J.
